* Small cleanup of context.exp.David Smith2010-03-241-15/+18
| | | | | * testsuite/systemtap.context/context.exp: Used "make -C $build_dir" to avoid using 'cd'. Added error handling.
* Update tests to check for uprobes instead of utrace.David Smith2010-03-092-4/+4
| | | | | | | * testsuite/systemtap.context/uprobe_stmt_num.exp: Change utrace test to uprobes test. * testsuite/systemtap.context/uprobe_uaddr.exp: Ditto. * testsuite/systemtap.base/bz5274.exp: Ditto.
* bz6436 backtraces from uprobesTim Moore2010-01-052-0/+17
| | | | | | | | | | | | | | | | | | | | | This implements proper unwinding from uprobes in the presence of uretprobe trampolines. * runtime/stack.c (_stp_stack_print): Rework for uprobe context case and refactor a bit. * runtime/uprobes2/uprobes.h (GET_PC_URETPROBE_NONE): new constant * runtime/uprobes2/uprobes.c (uprobe_get_pc): Support translating the trampoline function from uprobe context in addition to uretprobe context. * runtime/uprobes/uprobes.h (GET_PC_URETPROBE_NONE): ditto * runtime/uprobes/uprobes.c (uprobe_get_pc): ditto * tapsets.cxx (uprobe_derived_probe_group::emit_module_decls): Initialize ri in context to GET_PC_URETPROBE_NONE in generated enter_uprobe_probe. * testsuite/systemtap.context/fib.stp: Add an option to do a backtrace on function entry. * testsuite/systemtap.context/fib.exp: Test backtrace in function entry (uprobe) probes.
* support for a brief backtrace formatTim Moore2009-12-173-0/+85
| | | | | | | | | | | | | | This only prints symbol+offset, or an address if the symbol isn't known. * runtime/runtime.h (SYM_VERBOSE_NO, SYM_VERBOSE_FULL, SYM_VERBOSE_BRIEF): new constants * runtime/stack.c (_stp_stack_print): support brief format * runtime/sym.c (_stp_func_print): ditto * tapset/ucontext-unwind.stp (print_ubacktrace_brief): new function * testsuite/systemtap.context/fib.c: new test program * testsuite/systemtap.context/fib.stp: new test * testsuite/systemtap.context/fib.exp: new test
* backtrace through uprobes trampoline.Tim Moore2009-12-171-0/+31
| | | | | | | | | | | | | | Only works in uretprobes for the moment. * runtime/stack-x86_64.c (__stp_stack_print): Rewrite trampoline PC addresses if necessary. * runtime/stack-i386.c (__stp_stack_print): ditto * runtime/stack-arm.c (__stp_stack_print): Add extra argument * runtime/stack-ppc.c (__stp_stack_print): ditto * runtime/stack-s390.c (__stp_stack_print): ditto * runtime/stack.c (_stap_stack_print): call __stp_stack_print with uretprobe_instance. * testsuite/systemtap.context/uprobe_backtrace.stp: new test
* set the IP in return probes to the returned-to instructionTim Moore2009-12-162-0/+82
| | | | | | | | | | | | | | | | | | | | | | | | It's easily available in kretprobes and uretprobes and is consistent with the rest of the program state. * translate.cxx (emit_common_header) : add uretprobe_instance to context. * tapsets.cxx (common_probe_entryfn_prologue): Initialize ri in context to 0. (dwarf_derived_probe_group::emit_module_decls): Change IP to return address in kretprobes. (uprobe_derived_probe_group::emit_module_decls): enter_uretprobe_probe: set ri (uretprobe_instance) in context. Change IP to return address in uretprobes. Don't emit uprobe include and #define * runtime/runtime.h : Add includes and #define for uprobes. * runtime/stack.c (_stp_stack_print, _stp_stack_snprint): Add extra argument for uretprobe_instance. * tapset/context-unwind.stp (print_backtrace, backtrace): Pass NULL for uretprobe_instance to _stp_stack_print. * tapset/ucontext-unwind.stp (print_ubacktrace, ubacktrace): pass uretprobe_instance to _stp_stack_print * testsuite/systemtap.context/uprobe_uaddr.exp : new test for uaddr in function probes * testsuite/systemtap.context/uprobe_uaddr.stp : new file
* context.exp test improvements.David Smith2009-10-304-4/+6
| | | | | | | | * testsuite/systemtap.context/args.tcl: Increased timeout. If tests do timeout, fail (instead of silently failing). * testsuite/systemtap.context/num_args.tcl: Ditto. * testsuite/systemtap.context/backtrace.tcl: Increase timeout. * testsuite/systemtap.context/pid.tcl: Ditto.
* PR4186 cont'd: option #2: standardize on kernel ARCH/SUBARCH throughoutFrank Ch. Eigler2009-08-251-6/+3
| | | | | | | | * main.cxx (main): Perform equivalent sed by hand on uname()->machine. * stap.1.in: Clarify -a ARCH slightly. * tapsets.cxx (validate_module_elf): Accept "arm*"for EM_ARM. * tapset/**, testsuite/**: Removed/collapsed "i386"/"i686" branches, renamed "ppc64"->"powerpc" and "s390x"->"s390".
* Improved context.exp error handling.David Smith2009-08-113-10/+8
| | | | | | | | | | * testsuite/systemtap.context/context.exp: Makes sure errors are output to the log file. Also, a Makefile is copied with 'cp -p' to avoid make erroring out if the Makefile's date is in the future (as can be the case if running the test over nfs). * testsuite/systemtap.context/args.tcl: Makes sure 'close' errors are ignored. * testsuite/systemtap.context/backtrace.tcl: Ditto.
* PR10486 Raise default MAXSTRINGLEN.Mark Wielaard2009-08-071-2/+2
| | | | | | | | * translate.cxx (translate_pass): Raise MAXSTRINGLEN to 256 for 32bit arches and to 512 for 64bit arches. * testsuite/systemtap.context/backtrace.tcl: Don't set MAXSTRINGLEN. * testsuite/systemtap.exelib/ustack.tcl: Likewise. * testsuite/systemtap.string/str_replace.exp: Explicitly set MAXSTRINGLEN.
* Add testcase for PR10458, PR10459 and PR10454.Mark Wielaard2009-07-313-0/+102
| | | | | | | | Last test currently disabled because PR10454 is still open. * testsuite/systemtap.context/uprobe_stmt_num.exp: New file. * testsuite/systemtap.context/uprobe_stmt_num.stp: Likewise. * testsuite/systemtap.context/uprobe_stmt_num.c: Likewise.
* Fix arguments to mktemp with less than 6 X'sEugeniy Meshcheryakov2009-05-051-1/+1

* Add comment to try -d kernel -d systemtap_test_module1 on backtrace.tcl test.Mark Wielaard2009-04-201-0/+1
|
* Create usymname and usymdata variant that trigger STP_NEED_VMA_TRACKER.Mark Wielaard2009-04-071-3/+2
| | | | | | | | | * tapset/context-symbols.stp (syname, symdata): Pass NULL for kernel address. * tapset/ucontext-symbols.stp: New file defining usymname and usymdata. * testsuite/systemtap.context/usymbols.exp: Use usymname, remove STP_NEED_VMA_TRACKER hack. * testsuite/buildok/usymdata.stp: New test. * testsuite/buildok/usymname.stp: Likewise.
* PR6580: Implement symname, symdata and modname context functions.Mark Wielaard2009-04-021-1/+1
| | | | | | | | | | | | | | | | | | This adds a couple of the suggested context/stack revamp functions from PR6580. In particular it replaces the symbolname() function that sneaked in with the pr6866 branch merge with the suggested symname(). * runtime/sym.c (_stp_mod_sec_lookup): Make section optional. (_stp_symbol_snprint): Provide a way to get optional module info. * tapset/context-symbols.stp: Replace symbolname() with symname(), add modname() and symdata(). (probemod): Implement pc based fallback. * tapset/context-unwind.stp (caller): Adjust for _stp_symbol_snprint change. * testsuite/systemtap.context/usymbols.exp: Use new symname. * testsuite/buildok/modname.stp: New test. * testsuite/buildok/symdata.stp: Likewise. * testsuite/buildok/symname.stp: Likewise.
